Vanda plant named ‘SPCDW0901’

ABSTRACT

A new and distinct  Vanda  hybrid cultivar named ‘SPCDW0901’ is disclosed, characterized by unique purple coloration of the petals and overall, compact plant habit and unusual low temperature tolerance. The new variety is a  Vanda , and is normally used as an ornamental plant.

Latin name of the genus and species: Vanda hybrid.

Variety denomination: ‘SPCDW0901’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a chance, naturally occurring mutation of the unpatented commercial variety Vanda hybrid ‘Blue Magic.’ The inventor, Mr. Thumrong Suphachadiwong, a citizen of Thailand, discovered the new variety as a chance mutation among several hundred plants produced at a commercial laboratory in Chonburi, Thailand. The new variety was discovered in May 2003 by the inventor.

Asexual reproduction of the new cultivar ‘SPCDW0901’ by meristem tissue culture was performed at a commercial laboratory in Chonburi, Thailand later in 2003. Since that time, multiple generations have been reproduced, and have shown that the unique features of this cultivar are stable and reproduced true to type through successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW0901’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW0901.’ These characteristics in combination distinguish ‘SPCDW0901’ as a new and distinct Vanda hybrid cultivar:

-   -   1. Compact overall plant     -   2. Unique purple and white flower coloration     -   3. Unusually good tolerance for colder temperatures

PARENT COMPARISON

Plants of the new cultivar ‘SPCDW0901’ are similar to plants of the parent variety unpatented Vanda hybrid ‘Blue Magic’ in most horticultural characteristics. However, plants of the new cultivar ‘SPCDW0901’ produce purple and white colored flowers compared to the blue and white flowers of Blue Magic.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘SPCDW0901’ are similar to plants of the unpatented commercial variety, Vanda hybrid ‘Pink Magic’ in most horticultural characteristics. However, plants of the new cultivar ‘SPCDW0901’ produce purple and white flowers, whereas ‘Pink Magic’ produces pink and white colored flowers.

Plants of the new cultivar ‘SPCDW0901’ are similar to plants of the commercial variety, Vanda hybrid ‘SPCDW0902’ in most horticultural characteristics. However, plants of the new cultivar ‘SPCDW0901’ produce purple and white flowers, whereas ‘SPCDW0902’ produces white flowers. Additionally plants ‘SPCDW0901’ are taller and wider than plants of ‘SPCDW0902’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘SPCDW0901’ grown in a greenhouse. The pot size is a commercial 11 cm container. The plant shown is approximately 5 years old. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SPCDW0901’ plants grown in a commercial greenhouse in Honselersdijk, the Netherlands. Temperature ranged from 23° C. during the day and 19° C. at night. Light levels were at a minimum of 10,000 lux, including supplemental lighting given during naturally dark periods. During the naturally darkest days supplemental lighting of 10,000 lux was given for 16 hours per day. Measurements and numerical values represent averages of typical flowering types. No chemical or photoperiodic treatments were given.

-   Botanical classification: Vanda hybrid ‘SPCDW0901’.

PROPAGATION

-   Type of propagation typically used: Tissue culture. -   General propagation: The time needed from the start of a mericlone     to get the small plants ready for deflasking is approximately 24     months under a controlled temperature of about 26 degrees Celsius.     After that period they have matured roots. Young tissue culture     plantlets start to make roots after approximately 18 months in     flasks. -   Root description: Moderately to heavy rooting with aerial roots     only. Roots very fleshy, non-fibrous. Average length of old roots:     37.9 cm, average diameter of old roots: 2 mm. Average length of     young roots: 28.9, average diameter of young roots: 7 mm. Old roots     colored near RHS Yellow-Green 147C. Young roots colored near RHS     Greyed-Green 192D.
